Question

if the sides of a triangle are 17 cm ,25cm and 26cm . Find its area​

Answer 1

Answer:

204 cm^2 is your answer

Step-by-step explanation:

Area of triangle--- By using Heron's Formula,

$\sqrt{(s)(s - a)(s - b)(s - c)}$

Given :-

Sides of triangle = 17 cm, 25 cm and 26 cm

Perimeter = 68 cm

s = 68/2 = 34 cm

Now ,

Applying Heron's Formula

$\sqrt{34(34 - 17)(34 - 25)(34 - 26)}$

$\sqrt{34 \times 17 \times 9 \times 8}$

$\sqrt{41616}$

Area is 204 cm^2 .
